Specification of Letters Patent.

Application filed February 26, 1907. Serial No. 859.863.

To all whom it may concern:

Be it known that 1, WILLIAM ORENSHAW, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Guards for Edges of Concrete Paving; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

It is well known that asphalt or concrete paving of streets, as, for instance, adjacent the rails of a streetrailway, soon becomes worn and broken down, forming ruts, thus not only marring the appearance and preventing the best use of the street, but forming space in which decaying refuse may collect and remain, necessitating constant repair and unsightliness of appearance after repair. The breaking-down of the edges of concrete and asphalt paving of streets, adjacent the rails of a street-railway, as has been found, is due to vibration due to cars running over the rails.

The object, therefore, of my invention is to provide a device which, in use, prevents the communication of vibration from the railroad rail to the asphalt, and which, also, does away withthe usual, objectionable right-angle edge of the asphalt where it joins the rail, eliminating the impact of drayand truck-wheels, Which breaks down the edges of concrete paving adjacent the rails of a railway. And, by thus preventing the breaking down of the edges of the concrete paving, there is avoided the unsightliness and discomfort of broken surfaces, and there is saved the ensuing expense involved in repairing such broken surfaces.

Another object of my invention is to provide a device of this nature which shall be exceedingly simple of construction, most durable in use, and thoroughly eflicient for the purposes designed.

With these objects in view, the invention consists in the novel construction of a peculiarly-shaped guard adapted to be positioned in proximity to the vertical side walls of the top flanges of a railway-rail, whereby breaking down of the concrete-paving adjacent the rails is absolutely precluded.

For a more perfect understanding of my invention, attention is now invited to the accompanying drawing, in which Figure] is a perspective view of one form of my invention in use, showing the disposition thereof relative to a rail. Fig. 2 is a perspective view of a modification; and Figs. 3 and 4 are vertical sectional views of other modifications.

Referring to the drawings in detail, A indicates a railway rail of ordinary or any preferred construction, and forming no part of my invention.

Adapted to be positioned against the vertical wall of each top flange, a, o of the rail is the asphaltum edge-protector or guard of my invention, comprising a side, vertical wall b; a top flange b on one side of said wall and terminating, desirably, in a chisel-edge b and, desirably, a bottom flange b desirably on the same side of said wall as the flange b It is my intent to construct these guards in varying lengths, either straight or curved, so as to adapt them for use with rails of varying lengths, either straight or curved, or

whereby, for use with one rail, either one, or a number of, my guards may be used; and the guards or protectors may be made of any suitable material, either steel-plate pressed into the form shown, or of cast steel or cast malleable iron, and of desirably two and onehalf to three or more inches in width and of about that depth.

In use, one of my guards is placed on either side of the rail, with the vertical wall I) of the guard bearing against the side vertical wall of the flange of the rail A, with the upper or top flange b overlapping the concrete paving B and thereby protecting the same against breaking down, and with the lower or bottom flange b acting as anchoring-means against lifting of the device.

Referring to Fig. 2, disclosing a slightly modified form of device, it will be noted that the bottom flange b of the device of Fig. 1 is, in the device of Fig. 2, dispensed with and, in lieu thereof and subserving the same purpose and function, I form the top "flange b desirably at intervals, with cut-away portions b and, at the inner extremity of such cut-away portions, with depending angled portions 1), serving as anchoring means instead of the bottom flange b of the device of Fig. 1.

Referring to Fig. 3, disclosing another slightly modifled form of device, the top flange b carries teeth I), constituting anchoring means additional to the bottom flange b. It is designed that the top flange b shall advantageously carry a number of these teeth I), at intervals, constituting a series thereof.

Referring to Fig. 4, disclosing still another slightly modified form of device, the side wall b carries bolts or rods b desirably secured, as by being screwed into the side wall, and constituting anchoring means additional to the bottom flange b It is designed that the sidewall shall advantageously carry a number of these bolts or rods, constituting a series thereof. It may be desirable to use the bolt-anchoring feature for these guards or protectors that are made of pressed steel plate; but it is desirable to omit them, as being expensive, for guards made of cast steel or of cast malleable iron.

For guards or protectors made of cast steel, or of cast malleable iron, it may be more desirable to use the teeth-anchoring means shown in Fig. 3, as being simpler and less expensive than the bolt-anchoring means of Fig. 4. And it is obvious that a protector carrying teeth-anchoring means may be disposed on the inside of the rails and a protector carrying bolt-anchoring means may be disposed on the outside of the rails, or vice versa, as may be preferred or found best.

From the above description, taken in connection with the drawing, it will be seen that my device, dispensing, as it does, with the usual objectionable rightangled termination of asphaltum at the edge of railwayrails (which right-angled termination of the asphaltum is not sutficiently strong to withstand the impact of heavily loaded drays, trucks, etc), and protecting the asphaltum by transferring the point of impact from the place usually occupied by the right-angled formation, referred to, to the chisel-edge b, where the asphaltum forms practically a straight line, I overcome the breaking down of the asphaltum, the formation of holes and rats, and the disfiguring of the street, and I save the expense involved in repairs, at these points.

The protector or guard may be used in connection With any street-railway rail in use designed for positioning in asphaltum or concrete paving. The rail may be removed from the inside of the track without disturbing the protector at the outside, or, vice versa, the rail may be removed from the outside of the track, without disturbing the protector at the inside.

It will also be noted, that my protector will overcome the breaking down of the asphaltum at the rail, as it prevents the rasping and grinding action of iron-tired wagon-wheels on the asphaltum or other paving material, when the wheels of the wagon strike an elevated rail obliquely.

It will be understood, of course, that my device may be positioned at the edge of a sidewalk or curbing, or in analogous positions, or in any position desired for protecting the edges of asphaltuln or concrete paving, and preventing the breaking down thereof.

Without limiting myself to details oi construction, which come strictly within the scope and purview of my invention, what I claim as new is:

1. A guard for the edges of concrete paving, comprising a vertical wall, and a top flange on one side of said wall, said top flange being elongated widthwise and being ol gradually diminishing thickness towards its outer portion.

2. A guard for the edges of concrete paving, comprising a vertical wall, a lower flange on one side of said wall. and a top flange on the salne side of said wall. said top flange being elongated widthwise and being of gradually diminishing thickness towards its outer portion.

3. In combination with a railway-rail. a guard for the edges of concrete paving, comprising" a vertical wall. a lower flange on one side of said wall, and a top flange on the same side of said wall, said top flange being elongated widthwise and being of gradually diminishing thickness toward its outer portion.

In combination with a railnuiya'ail, a guard for the edges of concrete paving. comprising a vertical wall, a lower flange on one side of said wall, and a top flange on the same side of said wall, said top flange being, elongated widthwise and being oi: gradually diminishing thickness toward its outer portion, said guard carrying anchoring teeth.

In testimony whereof, I afllx my signature, in the presence of two subscribing witnesses.
